Question

Michelle sells umbrellas. 2 9 of her umbrellas are blue, the rest are red. 5 11 of the red umbrellas have plastic covers. What fraction of the Michelle's red umbrellas that do not have plastic covers?

Answer 1

Answer: 14/33

Explanation:

Since 2/9 of the umbrella are blue, the fraction for red umbrellas will be:

= 1 - 2/9

= 7/9

Since 5/11 of the red umbrellas have plastic covers. The fraction for those without plastic covers will be:

= 1 - 5/11

= 6/11

Therefore, the fraction of Michelle's red umbrellas that do not have plastic covers will be:

= 6/11 × 7/9

= 42/99

= 14/33
